The iPhone 7 was rumored to use fan-out wafer-level packaging technology in order to achieve a thinner and lighter model. [ 2 ] [ 3 ] [ needs update ] Wafer-level chip scale packaging (WL-CSP) is the smallest package currently available on the market and is produced by OSAT (Outsourced Semiconductor Assembly and Test) companies, such as ...
Advanced packaging [1] is the aggregation and interconnection of components before traditional integrated circuit packaging where a single die is packaged. Advanced packaging allows multiple devices, including electrical, mechanical, or semiconductor devices, to be merged and packaged as a single electronic device.
The steps involving testing and packaging of dies, followed by final testing of finished, packaged chips, are called the back end, [118] post-fab, [192] ATMP (Assembly, Test, Marking, and Packaging) [193] or ATP (Assembly, Test and Packaging) of semiconductor manufacturing, and may be carried out by OSAT (OutSourced Assembly and Test) companies ...
Integrated circuit packaging is the final stage of semiconductor device fabrication, in which the die is encapsulated in a supporting case that prevents physical damage and corrosion. The case, known as a " package ", supports the electrical contacts which connect the device to a circuit board.
This is known as a chip-first flow. Panel level packaging uses a large panel instead of a wafer to carry out the packaging process. [6] High end fan-out packages are those with lines and spaces narrower than 8 microns. [4] Fan-out packages can also have several dies, [5] and passive components. [6]
A semiconductor package is a metal, plastic, glass, or ceramic casing containing one or more discrete semiconductor devices or integrated circuits. Individual components are fabricated on semiconductor wafers (commonly silicon ) before being diced into die, tested, and packaged.
The BEOL process deposits metalization layers on the silicion to interconnect the individual devices generated during FEOL (bottom). CMOS fabrication process. Back end of the line or back end of line (BEOL) is a process in semiconductor device fabrication that consists of depositing metal interconnect layers onto a wafer already patterned with devices.
Integrated circuit packaging is the last assembly process before testing and shipping devices to customers. Occasionally specially-processed integrated circuit dies are prepared for direct connections to a substrate without an intermediate header or carrier. In flip chip systems the IC is connected by solder bumps to a substrate.
